The Japanese winger has been a big hit in Portugal since joining surprise package Portimonense in 2017, firstly on loan and then permanently.

Nakajima has contributed 15 goals and 19 assists in 47 games for the Portuguese side, which has turned the attention of several European clubs including Feyenoord.

However, Feyenoord would face plenty of competition for the 24-year-old, with Manchester United, Southampton, Deportivo Alaves, Real Mallorca and Freiburg all said to be looking at the Japanese international.
